Strengths and Limitations
- Top 3 strengths
- Most widely used and cited U.S. sea-level-rise viewer
- Explicitly communicates mapping uncertainty
- Includes marsh-migration projections most tools omit
- Top 3 limitations
- Does not include beach or dune erosion
- Static “bathtub” style mapping rather than dynamic storm modeling
- Not California-specific
